Specification of Letters Patent.

Patented June 29, 1915.

Application filed December 8, 1914. Serial No. 876,111.

To all whom it may concern Be it known that I, Tnorms W. DIXON, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State oflllinois, have invented certain new and useful Improvements in Vapor-Generators, of which the following is a specification.

My invention relates to improvements in gas generators adapted for use in conjunction with explosive engines, and has for its object the provision of an improved construction of this character which is simple and efficient in operation.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed. 7

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which,

Figure 1 is a view illustrating the construction as used in conjuction with an explosive engine, Fig. 2, a transverse section taken through a heating chamber employed in the construction, Fig. 3, a transverse section taken through a pressure tank employed in the construction, and Fig. 4:; a sectional view of a modified form of construction.

The preferred form of construction as illustrated in Figs. 1, 2 and 3 comprises a heating chamber 5 connected in the exhaust pipe 66 of an engine 7 so that the exhaust gases shall pass through said heating chamber. A tortuous pipe or coil 8 is arranged in said heating chamber 5 and is loosely filled with metallic particles 9. One end of coil 8 is connected by means of a pipe 10 with one end of a coil 11 arranged around exhaust pipe 6, as indicated, the other end of coil 11 being connected by means of a pipe 12 with the carburetor 13 of the engine. By this arrangement, it will be observed, that fuel passing through coils 8 and 11 will be thoroughly heated by the exhaust gases and corner-ted into a vapor ready for consumption by the engine. if desired the pipe 12 may be covered with suitable insulating material to prevent the escape of heat therefrom. Coil 8- is also connected by means of a pipe 1% with the bottom of a fuel tank 15, the upper portion of which. is connected by a pipe 16 with a pressure tank 1"? connected by of a pipe 18 u d; the exhaust pipe 6. Tani; 1"? is provided with an escape or safety valve 19 to prevent the accumulation of too much pressure therein-L By this arrangement, pressure from the exhaust pipe 6 will be transferred to pressure tank 17 and thence to the upper portion of fuel tank 15, serving to force the fuel through coils 8 and 11 to the engine, thus insuring an ample supply of fuel for the engine.

The form of construction illustrated in Fig. 4 is especially adapted for use where no inufller is employed. In this construction a casing 20 is arrangedv around the exhaust pipe 6 and filled with small metallic particles 21. Pipe 14 leading from the fuel tank 15 is connected with one end of casing 20. and the other end of said casing is connected by means of a pipe 22 with a coil 23 arranged in a casing 24 surrounding casing 20, the other end of coil 23 being connected by means of the pipe 12 with the carburetor of the engine. ltwill be observed that by this arrangement also, the fuel passing to the engine will be thoroughly heated and converted into a vapor for consumption.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

I claim:

1. The combination with the exhaust pipe of an explosive engine, of a casing connected to said pipe; a heating coil in said casing and filled with metallic particles; a coil surrounding the exhaust pipe and connected with said first mentioned heating coil; a fuel supply tank connected with said first mentioned heating coil; and means for connecting said last mentioned coil with the engine, substantially as described.

2-. The combination with the exhaust pipe of an explosive engine, of a casing inserted in said pipe; a heating coil within said casing and filled with metallic particles; means for connecting one end of said coil with an engine; a closed fuel tank connected with the other end of said coil; and a pressure tank connected with the exhaust pipe and with the upper portion of said fuel tank, substantially as described.

safety valve for said pressure tank, substanl tiall; as described.

Intestimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
